ESP32 NodeMCU

Problem:

Mit der Anschluss-Schaltung und Verdrahtung beim ESP32 wird das Pin GPIO2 verwendet. Dieser Anschluss ist beim Load nicht auf Null GND gezogen.

Für das Übernehmen des FLASH Speichers muss während des Upload das Pin auf GND gezogen werden.

Lösung:

Man muss das GPIO2 Pin zum Booten auf GND ziehen

Dann wird beim Download zum ESP32 das Programm richtig übertragen
